These benefits highlight the significance of setting up an ideal density of fish lifestyle applying BFT And just how crucial it really is to appreciate that Should the density of successful microorganisms exceeds the water purification ability, there may be an adverse impact on the fish. Dauda et al. [19] uncovered that the survival rates of C. gariepinus addressed with glycerol and sucrose-dealt with biofloc were ninety.six% and 76.three%, which ended up noticeably bigger than that with the control team (60.0%). Nonetheless, the survival price within the rice-bran-treated biofloc was discovered to generally be drastically reduce (27%) than that of your Manage, which may are actually mainly because of the insufficient carbon availability during the formation of biofloc. Therefore, it is crucial to work with an proper carbon source that is definitely appropriate for farm environments and cultured organisms when employing biofloc in fish society. Haridas et al. [twenty] reported that biofloc substantially improved the survival fee of gray mullet, Mugil cephalus, specially while in the nursery stage. In other reports, it's been reported that each biofloc and Manage teams showed either 100% survival or no significant big difference in the survival rate, which suggests that biofloc has an effect on bettering the immunity and health of fish but isn't going to usually show a big distinction.

क्या बायोफ्लॉक सिस्टम पर्यावरण के अनुकूल है?
Biosecurity measures: Implementing rigorous actions can avoid the spreading of diseases and parasites in fish farms. This involves suitable equipment disinfection, incoming fish checking, and isolation of sick fish.
नियमित परीक्षण: पानी के पीएच, तापमान और ऑक्सीजन के स्तर की नियमित रूप से जांच करें।
In Punjab, a few districts are using a utmost concentration of fish farmers They can be Gurdaspur, Bathinda, and Pathankot. A sample of about 100 fish farmers was chosen In accordance with their focus in selected districts by using chance proportional to dimension sampling technique.
) had been supplemented in BFT for that tradition of Nile tilapia. It resulted within an Improved mucosal and serum immunity towards pathogenic Streptococcus agalactiae
समाधान: नियमित पीएच परीक्षण और कार्बन स्रोत का संतुलित उपयोग करके उन्होंने समस्या का समाधान किया।
Cost-return Assessment of fish farming on sample fish farms disclosed that labor cost, energy utilization, diesel use from the irrigation system, and aeration cost were being the foremost constituents of variable cost. Whole variable cost per hectare was most on smaller fish farms, followed by medium and large farms which present the economies of scale.
इसी तरह की एक तकनीक है बायोफ्लॉक. इस तकनीक के जरिए किसान अधिक biofloc fish farming in hindi मछलियों का उत्पादन कर बंपर मुनाफा कमा सकते हैं.
No considerable change in temperature, overall ammonia nitrogen, whole phosphorus and NO2-N; decreased pH and dissolved oxygen
Water air pollution – In these, too many nutrients and nitrogen from foodstuff waste within the water stress the environment and also other fish.
The drinking water can be treated with probiotics, which will help to build an natural environment that may be conducive to The expansion of effective microorganisms.
बता दें रोजाना मछलियों के लिए पानी बदलना बेहद मुश्किल प्रकिया है. इस तकनीक के आने से किसानों को इस तकनीक से छुटकारा मिल सकता है. इसके अलावा मछलियों के प्रोटीन पर मछली पालकों को अलग से खर्च नहीं करना पड़ता है.
